2.5. 配置 install-config.yaml 文件

流程

1. 配置 install-config.yaml。更改适当的变量以匹配环境，包括 pullSecret 和 sshKey。

   apiVersion: v1
   baseDomain: <domain>
   metadata:
     name: <cluster_name>
   networking:
     machineNetwork:
     - cidr: <public-cidr>
     networkType: OVNKubernetes
   compute:
   - name: worker
     replicas: 2
   controlPlane:
     name: master
     replicas: 3
     platform:
       baremetal: {}
   platform:
     baremetal:
       apiVIP: <api_ip>
       ingressVIP: <wildcard_ip>
       provisioningNetworkInterface: <NIC1>
       provisioningNetworkCIDR: <CIDR>
       hosts:
         - name: openshift-master-0
           role: master
           bmc:
             address: ipmi://10.196.130.145?privilegelevel=OPERATOR 

   1

   
             username: root
             password: <password>
           bootMACAddress: 00:e0:ed:6a:ca:b4 

   2

   
           rootDeviceHints:
             deviceName: "/dev/sda"
         - name: openshift-worker-0
           role: worker
           bmc:
             address: ipmi://<out-of-band-ip>?privilegelevel=OPERATOR 

   3

   
             username: <user>
             password: <password>
           bootMACAddress: <NIC1_mac_address> 

   4

   
           rootDeviceHints:
             deviceName: "/dev/sda"
   pullSecret: '<pull_secret>'
   sshKey: '<ssh_pub_key>'

   bmc.address 提供了 privilegelevel 配置设置，值设为 OPERATOR。这是 IBM Cloud® Bare Metal (Classic)基础架构所必需的。

   为对应节点添加私有 provisioning 网络 NIC 的 MAC 地址。

   注意

   您可以使用 ibmcloud 命令行实用程序来检索密码。

   $ ibmcloud sl hardware detail <id> --output JSON | \
     jq '"(.networkManagementIpAddress) (.remoteManagementAccounts[0].password)"'

   将 <id> 替换为节点的 ID。

2. 创建用于存储集群配置的目录：

   $ mkdir ~/clusterconfigs

3. 将 install-config.yaml 文件复制到目录中：

   $ cp install-config.yaml ~/clusterconfigs

4. 在安装 OpenShift Container Platform 集群前，请确保关闭所有裸机节点：

   $ ipmitool -I lanplus -U <user> -P <password> -H <management_server_ip> power off

5. 如果以前的部署尝试中保留了旧的 bootstrap 资源，请删除旧的 bootstrap 资源：

   for i in $(sudo virsh list | tail -n +3 | grep bootstrap | awk {'print $2'});
   do
     sudo virsh destroy $i;
     sudo virsh undefine $i;
     sudo virsh vol-delete $i --pool $i;
     sudo virsh vol-delete $i.ign --pool $i;
     sudo virsh pool-destroy $i;
     sudo virsh pool-undefine $i;
   done
